Re: [ovs-discuss] ovs-2.8 Cannot open /dev/uio0

hi, That's because I'm using the Broadcom Nic for performing-test and found the uio problem("Cannot open /dev/uio0: Permission denied"). and I now RECHECKED the problem in my own VM environment。 Pity that, the uio Permission denied problem still alway exists.(the ovs2.7 is ok). and the

Re: [ovs-discuss] ovs-2.8 Cannot open /dev/uio0

Glad to hear that you solved the problem. What you have are Intel NIC - 82540em. The driver igb_uio should work for this - which is what you have. I am confused as to why you said that you were using Broadcom Nextreme card Anyways, it is good to hear that you were able to rectify the issue.

hi, I solved the NIC bind problem. I checked the log found that netdev_dpdk|ERR|Interface dpdk-eth2(rxq:1 txq:3) configure error: Invalid argument so, I changed the rxq of the NIC to 3 by "options:n_rxq=3", and it works. ^^ I tested the ovs2.8-dpdk in another VM of Centos7, but the

Re: [ovs-discuss] ovs-2.8 Cannot open /dev/uio0

I just want to use ovs-2.8 for userspace connection-track, and I choose the latest LST DPDK 1705. But, you mean theres is something like broadcom-uio.ko when using broadcom NIC? I just have changed the config/common_base: CONFIG_RTE_LIBRTE_BNX2X_PMD=y CONFIG_RTE_LIBRTE_BNX2X_DEBUG=y

Re: [ovs-discuss] ovs-2.8 Cannot open /dev/uio0

Is there a specific reason as to why you would want to use this version of DPDK? I have never had to check permission. Also, igb is mainly for Intel NICs. You are using a Broadcom NIC - http://dpdk.org/doc/guides/nics/bnxt.html for driver info. I think what you have is a misconfiguration. You
